SPECEIGATON forming part of Letters Patent No. 640,537', dated January 2, 1900. Application ined March 29, 1899. sensi no. 710,925. or@ mail) To @ZZ whom, it may concer-rt:

Be it known that I, CHESTER W. COTTRELL, of Newburyport, in the county of Essex and State of Massachusetts, have invented certain new and useful improvements in Lamp-Filling Devices for Lamp-Burners, of which the following is a description sufficiently full, clear, and exactl to enable those skilled in the art to which it appertains or with which it is most nearly connected to make and use the saine.

rlihis invent-ion has reference to means for facilitating the filling of kerosene and similar lamps.

It is the purpose of the invention to provide efficient and desirable means which will obviate the necessity of unscrewing and removing the wick and chimney-holder in order to refill the lamp by providing a burnerbase divided into two parts hinged together at one pointand latched together at another, so that by releasing the latch the parts may be swung apart on their hinge and the neck of the lamp opened to permit ot' ready reiilling, all as l will new proceed to describe and claim.

Reference is to be had to the annexed drawings and to the letters marked thereon, forming a part of this specification, the saine letters designating the same parts or features,

as the case may be, wherever they occur.

Of the drawings, Figure l is a side view of my invention, showing by dotted lines its relationship to a lamp. Fig. 2 is a plan view of the invention detached from a lamp. Fig. 3 is a vertical centralsectional view showing the parts as swung apart on their hinge, as they may be in filling the lamp.

ln the drawings in dotted lines, a designates the body and oil-reservoir of the lamp.

ZJ is the neck ot the lamp, through which it may be lled.

c is the burner, and d is the chimney.

It is in the base of the burner, which oonnects the latter with the neck l), that my improvements have been wrought. This connecting portion l make in two parts, or, as it were, as two members e and f, hingedly connecting the same at one side, as at h. The

opening through the member e is internally screw-threaded, as at g, so that the shank of the burner c may be screwed therein, and the open neck of the memberfis externally screwthreaded, so as to adapt it to be turned into the neck b of the lamp. The chimney d is to be attached to the burner, as shown, or in any other suitable way.

The internally-screw-tlneaded part of the member c may be integrally connected with the base-ring part, or it may be made as a separate part and soldered thereon or mechanically or otherwise connected therewith, and the same thing is true of the external1yscrew-threaded tubular neck of the member f, it being desirable when the members are closed, as shown in Fig. l, that theirsurfaces should match or iit fairly closely together.

One of the members-the member c, as herein represented-is shown as provided with a depending thumb-latch t, having a catchj, formed by pinching inward a portion of the metal composing the ear, and the other memberfis provided with a depending ear 7J, hav ing a hole Z, into which the catch j may take when the members are in closed position to latch them together. The latch fr' tits, of course, over the ear 7f3. As will be readily understood, the upper member is pressed down until the catch j comes opposite the aperture Z and automatically engages with said aperture. In order to open the base, it is simply necessary to press lightly outward upon the lower end of the latch i, thus disengaging tho catch j from the aperture Z, and thereby por mitting the upper member to be thrown back upon its hinge. Thus the operation of releas-- ing the catch and opening the hinge is pracn tically a single operation, since by my construction it is not necessary to provide or to operate any special device for either locking or unlocking the two members of the base.

It will now be seen that aburnerequipped with my improvements need not when it is proposed to fill a lamp be unscrewed from the neck b, but by simply taking hold ot the thumb-latoh` 'Il and lifting up thereon the two members c and f may be swung upon their hinge to the position shown in Fig. 3, the lamp filled, and the members latched together again, as shown in Fig. l.

It is to be noted that the improvements do not interfere with the sightliness or conveir IOO ience in the general use of the lamp, and that the invention is exceedingly simple in construction and most economic of manufacture.

Having thus explained the nature of the invention and described a way of constructing and using the same, though without attempting to set forth all of the forms inwhich it may be made or all of the modes of its use, it is declared that what is claimed is A base for a lamp-burner, comprising a lower member adapted to -be secured to the lamp and provided with a downwardly-projecting perforated ear, an upper member constructed to hold the burner hinged directly to said lower member and having a latch constructed to lie close against said ear when the base is closed, said latch being formed with i
